To @il wlt'ont it ma?) concerne:V

Be it known that I, JOHN I. Domini, a. citizen of the United States, residin at Phila delphia, in the county of Philade phia and State of Pennsylvania, have invented certain Yp Inl rovernents in Controller-Regulators, of` which the following is a specification.

This invention relates to the automaticregulation of the operations of electric-motor controllers, and its leading purpose is to provide in mechanism for intempting'the action and preventing the too rapid introduction of current a simplified construction of increased durability and efiiciencg.

In the accompanying drawings, igure 1 artially in section, represent- Fig. 2 is a veit-y tical sectional vienr of the construction shown in Fig. 1. Fi 3 is a vertical sectional view of a detail, ta en on the line 3 3 of Fig. i." Fig. 4 is a sectional lan view illustrating a modification inthe etailsof construction. Fig. 5 is a vertical sectional view of a detail, taken on the line 5 5 of Fig. 4; and Fi 6 is a vertical sectional view of a detail, ta en on theline OF 4.

.As shown in the drawings, the controllershaft 1, journaled in the top 2 of the controla disk or hood 4, irrnlyfixed to the shaft, ai

cosed sleeve into engagement with the shaft??V to secure these arts to ether and the shaft being revolved t rough t e hood by the handie 6. Within the hood is they circular chan# nei 7, having zigzag sections comprising the alternating and o positeiy-disposed Vrejections or teeth 8 amil), extending radin vvith reference to their ath of rotation. YYThe projections 8 have t e inclined faces Sgheing suitabl V-shaped, and the projections 9, disf posed tween the projections S, have the radial faces 9a and the curved faces 9", being of serrated form.

1n Figs. 1, 2, and Bthere is shovvnavvaylf)m in a member 1 i which is secured to the cas ing-tcp. A bali 12'lies normally in the inner part of the cam, Where its bifurcations 10* and 10" intersect, and in the channel Y inthe ath of the projections 8, both branches of e cam having an upward inclination in the `position to be'engaged by the second of the cani and in the c outward direction from their intersection. Therefore when the handle 6 is revolved in the direction of the arrow the ball is carried :by a projection 8 along the branch 10n into the ath of the succeeding rejection 9 which 1s engaged b the bali an theforwar movement o the andle is stopped. Upon relieve ing the pressure on the handle, so that the ball can disengage itself from the engaging pro-V jection 9, 1t rolls by gravity to its initial po'- sition into the path of the second rejection 8, which operiY the further revolution' ofthe'Y handle again throws the ball outwardly ro ection 9. In this Ymanner the desire inter ruptions are effected at the proper points ,in`

t e motor. in revoiving the handein theoV Besito direction to throw ofi the current t e all is thrown b the projections Sinto the cani branch lo, W ere it reci rocates through the actions of the incline faces 8Il and 9", from which it rolls, thus permitting an un-A interrupted reverse movement.

In Figs. 4, 5, and 6 the part 6V is provided l witha caniwa 13, having the elevation i3", Y

from theftop o which it inclines downwardly in the direction of the arrow to its part nearest 'the center of revolution of the channel?, Ythe haii' i2' normally restin in the ovvcst point annel in the path of- Vroest-,ions A8. in the forwsrdfrevolution or tlie andlfe to admit the current the projections 8 posh the Vhall l2 over the camselevaticn l'into'thepath of the alpproaching Erojectioiigjfhich engages the hal ,and therey ftiieYV movement. Upon moving thehandle in the reverse direction to erinit gravity in the 'direction of the arrow to its initial position in the path of the second rothe ball to pass it the bali will be carried bv l l jection 8,Which carries it into the path o the second projection 9. Thus there is effected a positive stepfhy-step movement in the forl- Ward directicnfor'the admission of current, whiie in the reverse movement for throwing oi the current the'hall aysn the camway since it will not positive y engage the inclined feces 8' and 9*'. Y i Having described. my invention, I claim* 1. A controlier-regulator com rising oppositcly-disposed alternating IDD prmections, a

cam, and a device movable by one into en gagement with another of said projections under control of said cam.

2. A. controller-regulator comprising a circular way having an irregular section, a movable device registering with said way for engagin,y irregularities of said section, and a cam or controlling the movement of said device.

3. A controller-regulator comprising a circular way having sets of oppositely-disposed projections, and a ball thrown bv one set into engagement with another set ci projections, said ball being auton'iaticallydiscngagcd from said last-named projections.

4; A- controller-regulator comprising oppositelydisposed alternating projections, a bah thrown by one into engagement with another of said projections and automatically disengaged from said last-named projections, and Ineens for controlling the Avmovements of said ball.

5. A controller-regulator comprising oppositely-dsposed alternating projections extendin radially with reference to the center of revo ution, a ball, and e way for controlling the movement of said ball, said ball being thrown horiaontall by one into engagement with another of sai projections and automatically disengaged from said last-named pron jections.

6. A controller-regulator com rising, in combination with the controllers aft, a device having a circular wa with oppcsitelydis osed projections fixe to and revoluble wit said shaft, a ball registering with said way andA throwny b v one into engagement with'another of sai projections, and a cam` for control-ling themovements of said ball.

7. A- oontnollen-regulator comprising in combination with the oontrollenshaft, a hood havingl a circular Waywith cppcsitel disposed rojections, a 4reciprocating evice thrown y one into 4engagement with another of said projections to check the revolution of said shaft said devicey being automatically disengaged, and means for controlling the movement of said device and permittingl said shaft toibo revolved freely in the reverse direction.

8. A controller-regulator comprising, in combination with the controllenshaft, a hood seas-ct provided with a circular way having a .set of substantially il-shaped projections and a set of substantially radial engaging surfaces, a reciprocating device thrown by said projections into cngagemerit with said surfaces and automatically withdrawn. from the path thereof in revolving 4said shaft in one direction, and moans whereby said shaft can be revolved freely in the opposite direction.

9. A. controller-regulator comprising, in combination with the oontrollcnshaft, a sot of substantially V-shapcd projections con nected to and revoluble with. said shaft, means providing subtantially radial surfaces alternating with said projections andvrevoluble therewith, a ball thrown by said projections into engagement with said surfaces, and a carnway for controlling-.the movements of said ball, said mechanism comprising means whereby the revolution ol' said shaft is interrupted in moving in one direction and is uninterrupted in moving in the opposite direction.

10. A controller-regulator comprisin in combination with the controller-shaft a liood having a circular way with substantialljvr shaped projections and corresponding irregu larities with substantially radial and inclined surfaces, a ball imrinally disposed in the ,path of said irojections and moved thereby indo the path of said substantiall" radial surfaces to check the rotation of sail' shaft in one direcn tion, and a camwayfor controlling the movement of said ball and enabling said inclined surfaces and projections to Fass it without positive engagement in revo ving said shaft in the opposite direction.

l1. A controllenregulator comprising, in combination with the controller-shaft, a ball, a way by which the movements of said ball are controlled, and means coacting therewith by which said ball is moved toward and from the center of revolution to effect an interruption of the movement of said shaft.

-In testimony whereof I have hereunto set i my name, this 5th day of January, A. D. 1906, in the presence oi" the subscribing witnesses.
